In an era when countries are increasingly exposed to the opportunities and risks associated with the rising global movement of people, policymakers are rethinking approaches to border controls and border management. These policies and programs run the gamut—from facilitating legitimate mobility of people and trade to thwarting unauthorized movements, the latter a significant preoccupation in the post-9/11 era and as publics have become ever less accepting of unauthorized immigration. The research offered here examines the management of borders, enforcement policies and initiatives, and border security technologies.

The South American immigrant population in the United States has grown at a faster rate than that of the overall foreign-born population, amid crises in Venezuela, Colombia, and elsewhere. Yet South Americans still account for only about one in ten U.S. immigrants. While they mirror the overall U.S. immigrant population in several demographic characteristics, there are some notable differences, as this article details.

The U.S. immigration enforcement system increasingly depends on other countries to help halt irregular movements through the Americas and accept the return of unauthorized migrants. Foreign governments play a crucial and yet underappreciated role in migration management, and can either aid or frustrate U.S. border-control aims, as this article explores.

A member of the Texas National Guard faces migrants in Eagle Pass, Texas.

Rising tensions between Texas and the federal government have sparked fears of a constitutional crisis after the state deployed its National Guard to prevent the U.S. Border Patrol from conducting operations in a city park in Eagle Pass, with Texas Governor Greg Abbott saying the “invasion” of migrants triggered the need for action. This article provides an overview of the standoff and the larger context of current and past state-federal tensions over immigration enforcement.

The number of Tibetan refugees in India, Nepal, and Bhutan has been on a steady decline since the mid-2000s, posing a threat to the future of an exile community that has developed a robust governance, cultural, educational, and religious structure. While the Tibetan government-in-exile has become a model for displaced communities, a series of factors have contributed to the shrinking population in South Asia, as this article describes.

Many countries are reopening for international travel and migration after the shutdown forced by the pandemic. Yet there is still no consensus on whether and how to use travel measures to prevent the spread of future variants of COVID-19 or respond to the next public health crisis. This commentary lays out four guiding principles for building an inclusive and effective global mobility system.

The population of sub-Saharan African immigrants in the United States is relatively small, but it has grown substantially over the last four decades and is likely to continue to increase.

Despite high hopes that international movement would be revived in 2021 after the deep chill in 2020 with designation of a global pandemic, cross-border mobility remained limited as migrants and travelers faced complex rules, high costs, and uncertainty as new COVID-19 variants emerged. This report assesses global mobility in 2021, including changing use of travel restrictions, their impacts on mobile populations, and efforts to safely restart migration and travel.

New Biden administration guidelines encourage immigration prosecutors to support dismissing many low-priority deportation cases and focus on criminals, threats to national security, and other priorities. This move could have a major impact on clearing backlogs in the overstretched U.S. immigration court system, resulting in quicker determinations in removal and asylum cases, where wait times can presently stretch for years.

Requirements that international travelers and migrants prove vaccination against certain diseases are about as old as vaccines themselves. In some cases, vaccine certificates predated the existence of government-issued passports. This article explores the history of these requirements, which began with smallpox and have since been applied for diseases including cholera, polio, yellow fever, and, recently, COVID-19.
